Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If encapsulated benefit agents are used to improve delivery efficiency, then benefit agent effectiveness is improved, but residual by-products (formaldehyde) are generated requiring additional scavenger materials
Solution Approach 1:
The patent extracts and removes shell particles containing residual by-products from the encapsulated benefit agent composition through filtration and centrifugation processes, separating the harmful fraction from the beneficial encapsulated agents
Solution Approach 2:
The patent converts the harmful residual by-products into removable shell particles that can be separated through physical processes, transforming a chemical contamination problem into a physical separation problem that eliminates the need for chemical scavengers
2Object-generated harmful factors
If scavenger materials are added to manage residual by-products, then by-product levels are controlled, but formulation complexity increases
Solution Approach 1:
The patent removes the need for scavenger materials by extracting and separating shell particles containing by-products through physical processes like filtration and centrifugation, simplifying the formulation by eliminating additional chemical components
Solution Approach 2:
The patent uses physical separation processes (filtration, centrifugation) as intermediary methods to remove by-products without requiring direct chemical interaction between by-products and scavenger materials, thereby avoiding formulation complexity
3Object-generated harmful factors
If scavenger materials are introduced to remove residual by-products, then by-product levels are reduced, but compatibility issues with other compositional components arise
Solution Approach 1:
The patent extracts shell particles containing residual by-products through physical separation methods, avoiding the introduction of scavenger materials that would have compatibility constraints with other compositional components
Solution Approach 2:
The patent replaces chemical scavenging mechanisms with physical separation mechanisms (filtration, centrifugation), eliminating compatibility issues between scavenger materials and other compositional components
